(CNN) — Both Todd Akin’s claim that women’s bodies can prevent conception in cases of “legitimate rape” and the GOP’s newly-adopted platform language calling for a constitutional ban on abortion have provoked controversy for largely the same reason: They showcase the belief that all abortions should be illegal, without exception.

But even as Democrats and abortion rights groups use the controversies to reinforce allegations of a Republican-led “war on women,” don’t expect the anti-abortion movement to back away from calls for all abortions to be illegal — even for women impregnated by rape or incest.

“Philosophically, the consensus is very clearly that life is life and that it should be not be taken and that abortion is not a compassionate response to something terrible, even like rape,” said Marvin Olasky, the editor in chief of World magazine, an influential evangelical publication.
